Census of Population and Housing, 1990 [United States]: Public Law (P.L.) 94-171 Data (ICPSR 9516)

Principal Investigator(s):
United States Department of Commerce. Bureau of the Census

Summary:

Public Law 94-171, enacted in 1975, requires the Census
Bureau to provide redistricting data in a format requested by state
governments. Within one year following the Decennial Census (by April
1, 1991), the Census Bureau must provide the governor and legislature
of each state with the population data needed to redraw legislative
districts. To meet this requirement, the Census Bureau established a
voluntary program to allow states to receive data for voting districts
(e.g., election precincts, city wards) in addition to standard census
geographic areas such as counties, cities, census tracts, and blocks.
These files contain data for voting districts for those counties for
which a state outlined voting district boundaries around a set of
census blocks on census maps, in accordance with the guidelines of the
program. Each state file provides data for the state and its subareas
in the following order: state, county, voting district, county
subdivision, place, census tract, block group, and block. Additionally,
complete summaries are provided for the following geographic areas:
county subdivision, place, consolidated city, state portion of American
Indian and Alaska Native area, and county portion of American Indian
and Alaska Native area. Area characteristics such as land area, water
area, latitude, and longitude are provided. Summary statistics are
provided for all persons and housing units in the geographic areas.
Counts by race and by Hispanic and non-Hispanic origin are also given.
